Wholesale of explosion-proof control cabinets

Sensor explosion-proof positive pressure cabinet dust explosion-proof control cabinet

Product Features
1.This product mainly consists of a cabinet, an automatic control system, a gas distribution system, an alarm system, and a power distribution system; The cabinet consists of a positive pressure chamber and a secondary chamber. The positive pressure chamber houses the user's power distribution system components, while the secondary chamber houses the automatic control system.
2.Cabinet style products adopt“Second worker”Cabinet frame, main and auxiliary panels are of left and right structure, upper and lower structure, piano table, etc. They are installed in cable trench socket, with bottom incoming lines and front door operation, and front or rear door maintenance.
3.Box type products are made of high-quality steel plates or stainless steel welded structures. The main and auxiliary panels are of upper and lower structures, with hanging installation, lower incoming lines, front door operation and maintenance.
4.The piano table product is made of high-quality steel plate folded and welded into shape. The main and auxiliary plates are front and rear structures, installed in a seated manner, with bottom inlet and piano table operation, and rear door maintenance.
5.Divided into ventilation type and compensation type according to the intake method. The ventilation type is an uninterrupted continuous gas supply, and the working heat of the components installed in the positive pressure chamber can be carried away with the air path, which has good heat dissipation function and is suitable for solving the heat dissipation problem of high-power explosion-proof frequency converters; Compensation type is intermittent gas supply, and the positive pressure chamber should have good sealing to ensure low gas consumption.
6.The user must provide a gas source, which requires purified air or nitrogen, with a gas source pressure of:0.2～0.8MpaUsually, the instrument air at the user's site can meet the requirements.
7.Steel plate materials are generally usedGB710-88Cold rolled steel plates can also be selected according to user requirementsGB3280-84Stainless steel material.

PXKSeries positive pressure cabinet
1.The product is equipped with a ventilation interlock. Before the product is put into operation, only after passing through the main panel cavity for ventilation and reaching the specified ventilation time and volume, can the secondary panel be powered on and the main chamber pressure be detected to ensure that the electrical components have been effectively isolated by clean media.
2.Only when the internal pressure of the main panel meets the specified pressure requirements, will the automatic power switching system in the auxiliary panel supply power to the main panel.
3.The working pressure inside the main disk cavity is100Pa≤P≤1000Pa.
When the air pressure is higher than1000PaAt this time, the self-control system automatically closes the intake or opens the exhaust valve, adjusts the internal air pressure automatically, and ensures that the product is not deformed or damaged by high air pressure impact.
When the air pressure is lower than100PaAt this time, the automatic control system will sound an alarm and turn on the intake, automatically adjusting the internal air supply. When the air supply is successful, it will automatically return to normal. If it is unsuccessful, the internal air pressure will drop to60PaIf necessary, the system can be set to automatically power off.
4.The auxiliary disk self-control system is an uninterrupted continuous monitoring system that displays various pressure parameters inside the main disk cavity.
